Other rights. Moral rights, such as the right of integrity, are not licensed under this Public License, nor are publicity, privacy, and/or other similar personality rights; however, to the extent possible, the Licensor waives and/or agrees not to assert any such rights held by the Licensor to the limited extent necessary to allow You to exercise the Licensed Rights, but not otherwise.

Where the Licensed Rights include Sui Generis Database Rights that apply to Your use of the Licensed Material: for the avoidance of doubt, Section 2(a)(1) grants You the right to extract, reuse, reproduce, and Share all or a substantial portion of the contents of the database for NonCommercial purposes only and provided You do not Share Adapted Material; if You include all or a substantial portion of the database contents in a database in which You have Sui Generis Database Rights, then the database in which You have Sui Generis Database Rights (but not its individual contents) is Adapted Material; and You must comply with the conditions in Section 3(a) if You Share all or a substantial portion of the contents of the database. For the avoidance of doubt, this Section 4 supplements and does not replace Your obligations under this Public License where the Licensed Rights include other Copyright and Similar Rights.

This includes, without limitation, warranties of title, merchantability, fitness for a particular purpose, non-infringement, absence of latent or other defects, accuracy, or the presence or absence of errors, whether or not known or discoverable. Where disclaimers of warranties are not allowed in full or in part, this disclaimer may not apply to You. To the extent possible, in no event will the Licensor be liable to You on any legal theory (including, without limitation, negligence) or otherwise for any direct, special, indirect, incidental, consequential, punitive, exemplary, or other losses, costs, expenses, or damages arising out of this Public License or use of the Licensed Material, even if the Licensor has been advised of the possibility of such losses, costs, expenses, or damages. Where a limitation of liability is not allowed in full or in part, this limitation may not apply to You. The disclaimer of warranties and limitation of liability provided above shall be interpreted in a manner that, to the extent possible, most closely approximates an absolute disclaimer and waiver of all liability. Section 6 – Term and Termination. This Public License applies for the term of the Copyright and Similar Rights licensed here. However, if You fail to comply with this Public License, then Your rights under this Public License terminate automatically. Where Your right to use the Licensed Material has terminated under Section 6(a), it reinstates: automatically as of the date the violation is cured, provided it is cured within 30 days of Your discovery of the violation; or upon express reinstatement by the Licensor. For the avoidance of doubt, this Section 6(b) does not affect any right the Licensor may have to seek remedies for Your violations of this Public License. For the avoidance of doubt, the Licensor may also offer the Licensed Material under separate terms or conditions or stop distributing the Licensed Material at any time; however, doing so will not terminate this Public License. Sections 1, 5, 6, 7, and 8 survive termination of this Public License. Section 7 – Other Terms and Conditions. The Licensor shall not be bound by any additional or different terms or conditions communicated by You unless expressly agreed. Any arrangements, understandings, or agreements regarding the Licensed Material not stated herein are separate from and independent of the terms and conditions of this Public License.

To the extent possible, if any provision of this Public License is deemed unenforceable, it shall be automatically reformed to the minimum extent necessary to make it enforceable. If the provision cannot be reformed, it shall be severed from this Public License without affecting the enforceability of the remaining terms and conditions. No term or condition of this Public License will be waived and no failure to comply consented to unless expressly agreed to by the Licensor. Nothing in this Public License constitutes or may be interpreted as a limitation upon, or waiver of, any privileges and immunities that apply to the Licensor or You, including from the legal processes of any jurisdiction or authority.

Geo-Biochemical properties of peroxidase extracted from Cola nitida At the Ninth Year of Planting
Abstract
Background: This study reports the biochemical properties of plant peroxidase from white cultivars of Cola nitida for sustained biotechnological applications.
Methods: Peroxidase was extracted from Cola nitida, in 20 mM sodium phosphate buffer pH 7.0 containing 10% glycerol, 1% PEG, , 0.015% citric acid, 0.010% L-Cysteine and 0.010% ascorbic acid Buffer C). The extracted peroxide was subjected to a step wise purification stages which separated it into two peaks. The native molecular weight was determined for the major peak to be 21 ± 1.16 kDa while the subunit was estimated to be 15.5 ± 2.1 kDa.
Results: Optimum pH and temperature was studied to be 4.0 and 40oC respectively. Further studies required investigating several methods of immobilization on the nine years harvested Cola nitida in order to enhance its biotechnological applications.
Conclusion: However, this study was able to establish that Cola nitida is a strong alternative to the commonly purchased horseradish peroxidase.
